Vulcan's Revenge by pauljoda
Vulcan's sword was his pride and joy, then one day an adventurer broke it, sealing him away forever.
Bone Armor Mod by monkeyfunk26
Adds new craftable armor sets and tools. Introducing: Bone and Withered Bone armors! Look like a Skeleton, or a Wither Skeleton - but wait, there's more! Recipes, natural drops, balanced armor (with effects), swords (one with a potentially life-threatening effect imbued) can be made. Oh, but it's not that easy. The Withered Bone armor and tools can only be made by applying some Solution of Wither, something that isn't too easy to come across. Enjoy!
